| [16:00] <tomwardill> surprise, it's iptables! | |
| [16:01] <SpecialK|Canon> lol | |
| [16:18] <tomwardill> \\ø/ finally done it | |
| [16:18] <tomwardill> for future travellers: lxd has a defualt forward accept policy that deliberatly preceeds ufw rules | |
| [16:20] <tomwardill> which is obvious, in retrospect | |
| [16:21] <SpecialK|Canon> nicely found | |
| [16:22] <SpecialK|Canon> most things are obvious in retrospect - that's how retrospect works ;) | |
| [16:22] <tomwardill> iptables -S shows the FORWARD rules, which are higher in the list than the ufw ones | |
| [16:23] <tomwardill> `lxc network set lxdbr0 ipv4.routing false` will change it to a DENY | |
| [16:23] <tomwardill> or you can manually delete the rules | |
| [16:23] <tomwardill> I think there's config somewhere, but not found it yet | |
| [17:14] <cjwatson> Sigh, first breezy regression (issue with inline comments containing unicode) | |
| [17:15] <cjwatson> Well not a regression in breezy itself, regression caused by a bit of my port | |
| [17:19] <tomwardill> Build log: sendto(ntp.buildd): Operation not permitted | |
| [17:19] * tomwardill gradually finds all the things that are now failing | |
| [17:22] <cjwatson> tomwardill: I usually set "ntphost =" in /etc/launchpad-buildd/default for a local builder | |
| [17:22] <cjwatson> Since you probably don't have an ntp.buildd anyway | |
| [17:22] <tomwardill> I just /etc/host'd it to ntp.ubuntu.com | |
| [17:22] <cjwatson> Can't be proxied though | |
| [17:23] <cjwatson> So either allow it or change config to not use it | |
| [17:23] <tomwardill> yeah, I've also allowed it in ufw | |
| [17:42] <cjwatson> Aha, tests didn't catch this because they tried to use \u inside a str | |
| [17:42] <cjwatson> Python 2 string (bytes) literal that is | |
| [17:42] <cjwatson> Where \u1234 corresponds to the bytes \ u 1 2 3 4 | |
| [17:44] <SpecialK|Canon> I...yikes | |
| [17:44] <cjwatson> Nice landmine | |
| [17:52] <cjwatson> https://code.launchpad.net/~cjwatson/launchpad/+git/launchpad/+merge/378414 | |
| [17:57] * SpecialK|Canon does some obligatory Hypothesis flag-waving | |
| [17:58] <cjwatson> I've occasionally thought about it, yes. Would need to take some care to apply it only to true unit tests though - it would probably get prohibitively slow for anything that talks to the database | |
| [17:59] <SpecialK|Canon> Oh absolutely | |
| [17:59] <tomwardill> Temporary failure resolving 'archive.ubuntu.com' | |
| [17:59] <tomwardill> no. | |
| [17:59] <tomwardill> networks. | |
| [17:59] <SpecialK|Canon> hugops | |
| [17:59] <tomwardill> stop it. | |
| [17:59] <cjwatson> (Well, maybe. If the database tests were in the happy path that can just ROLLBACK between tests rather than having to clone a fresh template then maybe. | |
| [17:59] <cjwatson> ) | |
| [17:59] <cjwatson> .oO( PITR for the test suite ) | |
| [18:00] <SpecialK|Canon> ooh | |
| [18:00] <cjwatson> Would that work I wonder? I don't know enough about how PITR works | |
| [18:01] <SpecialK|Canon> I only know of it as a concept (so sure, if we can, then yay) but it sounds like you're thinking of a specific impl? | |
| [18:02] <cjwatson> Probably not actually faster though. I think if you're doing PITR then you have to replay WAL forwards, not backwards | |
| [18:03] <cjwatson> So the situation that requires cloning a fresh template is when a test has committed a transaction, since then you can't just roll back to get to a clean state | |
| [18:04] * tomwardill -> EOD to somewhere that doesn't involve computers :) | |
| [18:04] <cjwatson> If we could rewind time using WAL on disk then that would be faster | |
| [18:04] <cjwatson> But I think that isn't really how it works, sadly | |
| [18:09] <SpecialK|Canon> something something time travel something | |
| [18:11] <cjwatson> https://www.postgresql.org/docs/10/app-pgrewind.html is a thing ... | |
| [18:12] <cjwatson> May be worth experimenting at some point to see if it's faster | |
| [18:27] <SpecialK|Canon> Will have a read next week - sounds neat! | |
| [18:27] * SpecialK|Canon EOWs, take care y'all | |
| [18:31] <pappacena> See ya, Kristian | |
| [19:23] <roadmr> SpecialK|Canon ???? | |
